Application filed May 22, 191% To all whom it may concern:

Be it known that I, Gus F. Romances, a citizen of the United States, residing in Fries, in the county of Grayson and State of Virginia, have invented certain new and useful Improvements in Cleaners for Spinning-Machines, of which the following is a specification.

The object of my invention is to provide improved means for removing from the frames of spinning machines lint which ordinarily accumulates on the thread-boards, roller beams, back boards and creels of such machines during the operation of the mechanism. Devices for this purpose have here tofore been suggested but so far as I am aware they have not satisfactorily performed the operation for which they were intended and have had only avery limited use. I have provided means for this pur' pose which are not only simple in construction and in operation, but which experience has demonstrated most efficiently keep the thread-boards, creel and other parts of the machine clear of lint, fly and similar substances which would tend to interfere with the operation of spinning.

In carrying out my invention I provide for each thread-board and for the creel an endless cord carrying brushes or wipers which are made to traverse the entire length of the thread-board or creel and to remove the lint and other foreign matter therefrom. Each cord is guided by suitable pulleys and is weighted with a uniform tension to keep it straight and to cause it to move with uniformity in one direction in a fixed path. The wipers or brushes carried over the thread-board and the creel in this way remove the lint, etc., therefrom, which lint adheres not only to the wipers or brushes but also to the cords and in order to clear the wipers and cords from lint adhering thereto I provide brushes which engage the cords and wipers and detach the lint therefrom. Mechanism is provided which drives the cords and the brushes from the power shaft of the spinning machine, the brushes being by preference rotary and driven at a high speed. The wipers carried by the cords also serve to keep clean the roller beams and back boards of the machine, as well as the thread boards and creel.

In the accompanying drawings I have shown my invention applied to a spinning Specification of Letters Eatent.

machine of well known construction and I will describe my invention as so applied. Obviously however my improvements may be applied to twisting machines, to fly frames, and to similar mechanism.

Figure 1 shows an end elevation of a spinning machine with my improvements applied. Fig. 2 is a perspective view with parts broken away of such machine clearly illustrating how my improvements are embodied therein. Fig. 3 is a detail view of the gearing which connects the cord-driving mechanism with other parts of the machine. F ig. 4 is a detail view of the driving mechanism for one of the brushes. Fig. 5 shows an end elevation, on a reduced scale, of a shield employed at one end of the machine. Fig. 6 shows a vertical section of the shield attached to one end of the lower creel board. One of the end pieces of the spinning machine is indicated at A.

B, B indicate the thread-boards, B the roller beams, 13 the back boards, and C the creel. In this instance a double creel is shown comprising the lower creel board C and the upper creel board C The drawing rolls are indicated at D. The roving bobbins are indicated at E and the spindles which receive the threads from the drawing rolls are indicated at F. Each of the thread-boards is provided with a cleaner consisting of an endless cord G which extends around pulleys g at one end of the frame which spreads the cord into two parallel members and at the other end of the frame the cord extends over pulleys g and from thence downwardly across the end of the frame where the loop formed thereby supports a weighted pulley H. The cord Gr carries wipers or cleaners a; which are held close to the thread-board by the cord and operate to clean this board. Each of the thread-boards is provided with a cleaner, and this cleaner also serves to clear the adjacent roller beam and back boardv of lint. The lower creel board (1 is provided with a similar cleaner but as I have in this instance shown a creel comprising upper and lower board C, G I have so arranged the cord I that it carries the wipers or cleaners over both the upper and lower boards of the creel.

Tracing the cord from the weighted pulley J it will be seen that one branch thereof first passes over the pulley j on the framepiece A, then longitudinally over the lower creel board C, then under a pulley j on the opposite end of the lower creel board, then upwardly to a pulley j on the adjacent end of the upper creel board, then longitudinally over the upper creel board to a pulley 9' then crosswise of the upper creel board to a pulley y, thence backwardly and longitudinally across the upper creel board in a line parallel with the other longitudinal portion of the cord, then over a pulley 7' downwardly to a pulley j on the adjacent end of the lower creel board, then longitudinally across the lower creel board to a pulley 7' and then to the weighted pulley J. The cord I carries a suitable number of wipers or cleaners 2'.

In order to drive the cords G and I from a single shaft I provide the mechanism illustrated in Fig. 2. This comprises a horizontally arranged shaft K mounted in suitable hearings in the frame of the machine and carrying pulleys is across or under which the cords G and I extend as shown. The cords also pass through or over idlers or sheaves in which are suitably attached to the machine frame. The shaft K is of course located below the thread-boards, roller beams and back boards, and the pulleys it serve to divert the course of the cords downwardly into engagement with the driving pulleys 7c. The shaft K is driven by a shaft L carrying a beveled pinion Z engaging a corresponding pinion Z on the shaft K. The shaft L may be driven inany suitable way. As indicated in Fig. 3 it is connected by a train of gearing Z with a shaft Z carrying a large spur wheel Z which may be connected in any suitable way with the power shaft. In this way the cords may be'driven at the desired speed to carry the wipers across the creel, back boards, roller beams and thread-boards in the manner indicated by the arrows, and in this way the boards and beams will be kept clean, all lint and other similar substances being carried to the ends of the machine where it is detached from the cords and wipers by the brushes and dropped.

It is necessary to provide means for detaching the lint from the cords and wipers at a point outside of and away from the stock and working parts of the machine, and in order to do this I employ brushes of suitable construction and operation. Preferably I use rotary brushes M of the kind shown. These brushes are mounted to rotate on one of the end frames A. and to engage the vertical portions of the cords G and I preferably in the manner indicated in Fig. 2. These brushes may be driven in any suitable way, preferably by means of belt-gearing N driven from a pulley n ona shaft 0 which may be the power shaft of the machine. The mechanism is all operated automatically and at proper speed to most efficiently clear the machine from lint and to detach from the cords and wipers the lint accumulated by them.

The mechanism is so operated as to quietly and gently move the lint over the surface of the boards and carry it down to one end of the machine and the brushes are located below the plane of the threadboards, and therefore when the lint is detached from the cleaners by the brushes it does not tend to settle back upon the boards, stock or working parts of the machine. It will be observed that a single cord is employed for cleaning both the upper and lower creel boards.

It will be understood that the cleaning cord extends from one end of the frame of the machine to the other. These frames are usually of great length. In some cases the length is thirty feet or more and therefore the cord for a thread-board is often over sixty feet in length. Such cord, I have found, is best made of cotton and owing to its length the expansion and contraction due to different atmospheric conditions is considerable. It is important, of course, that the cord should be held taut at all times and under all conditions, and one of the important features of my invention is the weighting of the cords in the manner illustrated. In this way the traverse of the cords over the thread-boards and over the creel boards is not interfered with in any way, but uniformity is promoted owing to the uniform tension that is provided.

The wipers a; are preferably made of cloth such as flannel but they may be made of any suitable material and may be attached to the cords in any suitable way.

The lint detached from the cords and wipers by the brushes is prevented from floating back to the top of the machine by a shield T which may be attached to the end of the lower creel board C as indicated at t in Fig. 6. The shield is formed with recesses t, t to allow the cleaning cords to pass, and it is of such size as to cover the end of the creel above the brushes M.

It will be observed that each outside cord with its wipers cleans a thread-board. roller beam and backboard, while the middle cord cleans both the upper and lower parts of the creel.

The lint which flies away from the stock being operated upon ordinarily remains suspended in the air for ashort time and then settles back on the thread-boards, roller beams, back-boards and creel and on the floor. The usual practice is to clean these boards by hand every twenty or thirty minutes after there has been considerable accumulation of lint as otherwise the lint would catch in the thread being spun and make lumps or enlargements on it which Li -29,3 i2

would interfere with the spinning operation. This operation has to be very carefully performed. By my improvements, no great accumulation of lint is possible as in practice the machine is cleaned every sixty. or eighty seconds and no such accumulation of lint or fly as would interfere with the spinning operation occurs. Inasmuch as the cords and wipers continuously traverse the machine the amount of lint accumulated during each circuit of the cleaners is comparatively small and is easily removed by the brushes which are so located that the lint thus removed cannot float back and settle on the working parts of the mechanism.
